FIBER STRETCHERS

Piezomechanik GmbH manufactures piezo-based fiber stretchers for piezomechanical modulation of the fibers' optical properties. A standard arrangement uses large-diameter piezo tubes wrapped with layers of fibers. The piezo-actuated fiber can be up to 15 m in length, resulting in a stretching efficiency of approximately 5 µm/V. The operating range of the piezo tube is -200 to +1000 V.
